3.1 Wide application
The Full DC Inverter individual VRF system is a highly efficient solution for small commercial buildings
requiring heating and cooling of up to 12 zones with one outdoor unit. Such as villa, restaurant, school etc.
Sinclair offers a variety of indoor unit, more than 40 models of 7 types. Capacity ranges are from 1.5kW to
16kW. It is full compliance with residential and light commercial place. Our systems can operate up to 130% of
capacity which allows any system to be designed to the customers’ and applications’ needs.

3.2 High efficient DC inverter compressor
.Full DC inverter Individual VRF adopts highly intelligent inverter-driven compressor. This advanced technology enables the
output of the outdoor unit to be modulated by the real heat load demands.
This advanced system ensures precise temperature regulation and highly efficient energy usage, making a significant
contribution to the limiting the impact on the environment.
3.3 High performance heat exchanger
The new designed window fins enlarge the heat-exchanging area ,
which decrease the air resistance, save more power and enhance heat
exchange performance.
Hydrophilic film fins and inner-threaded copper pipes optimize heat
exchange efficiency.
3.4 Low-operating sound design
Optimally design fan shape and new designed discharge air grille and air deflector, making higher air volume and lower operation
sound.
3.5 Quick warm-up & cool-down design and less temperature fluctuation
Utilizing the inverter compressor benefits,
the system can reach full load quickly and
shorten warm-up or cool-down time for an
immediate comfortable air solution.
Less temperature fluctuation will create a
better living environment.
Highly Efficient DC Motor:
- Creative motor core design
- High density neodymium magnet
- Concentrated type stator
-Wider operating frequency range
Better balance and Extremely Low Vibration:
- Twin eccentric cams
- 2 balance weights
Highly Stable Moving Parts:
- Optimal material matching rollers and vanes
-Optimize compressor drive technology
- Highly robust bearings
-Compact structure

3.6 Wide operation temperature range
No matter in extremely cold winter when outdoor
temperature gets as low as -15°C or in hot summer
when temperature is up to 48°C, the individual VRF
system will keep stable performance.
3.7 Flexible piping design
3.8 Flexible indoor unit’s connection
Individual VRF with intelligent control gives you independent zoning control with maximum flexibility.
A single outdoor unit supports up to 12 indoor units, freeing up considerable space outside. Use your backyard more wisely with
much more space available created by less number of outdoor units.
Max. 10 indoor units for a 20kW outdoor unit installation
Max. 11 indoor units for a 22.4kW outdoor unit installation
Max. 12 indoor units for a 26kW outdoor unit installation
3.9 Simple signal line connection
Installation is much easier as the communication wiring between indoor & outdoor units can be shared.
It’s easy for the user to retrofit the existing system with a centralized control by simply connecting to
outdoor unit.
3.10 Auto address setting function
The addresses of indoor units can be set automatically by outdoor unit.
Wired controller and wireless controller can enquire and modify the address of each indoor unit.
